Sea Change-US's first hydrogen-powered ferry SWITCH Maritime's new 70-foot passenger ferry Sea Change is the first zero-emission, hydrogen fuel cell-powered electric ferry sailing in unknown waters.

The groundbreaking new aluminum vessel built by All American Marine, Inc. (AAM) at Bellingham Shipyard in Washington State was completed and launched this summer, but the U.S. Coast Guard is still drawing up regulations that allow marine vessels to use hydrogen fuel systems. problem.

"For this type of ship, passenger safety legislation and laws do not yet exist. Therefore, working with the Coast Guard to develop a set of rules to simplify this process in the future is a necessary challenge to promote the adoption of any new technology," AAM President Said Ron Wille and Chief Operating Officer.

The project is funded by private capital from SWITCH, which is an impact investment platform that aims to build a fleet of zero-carbon sea ships. "By working closely with the US Coast Guard, innovative technology partners, and leading shipyards such as All American Marine, we can achieve the transition to decarbonized shipping today," said co-founder and CEO Pace Ralli. change. "We don't have to wait."

The first Sea Change is equipped with a hydrogen fuel cell power package provided by Zero Emission Industries (formerly Golden Gate Zero Emission Ship), which is powered by a 360 kW Cummins fuel cell and a capacity of 246 kg. The system integrates a 100 kWh lithium-ion battery provided by XALT and a 2x 300 kW electric propulsion system provided by BAE Systems. The ship design originated from Incat Crowther, and the construction supervision and management was led by the Hornblower Group.

The USCG Subchapter T can accommodate 78 passengers and can be operated by two crew members. The ship includes ramps leading to the bow and side loading doors to provide access for the disabled. The bow adopts a standard bow radius, which is suitable for many American cities, and the elevated wheelhouse provides an excellent view for bow loading operations. The top speed of Sea Change can reach 20.5 knots.

Wille of AAM stated that he believes that hydrogen fuel cell technology will surpass traditional diesel and hybrid electric propulsion methods and become the most conducive method for offshore applications. "We see this fulcrum for many reasons, but the main reason is that it is both transportable and has a very high energy density. Compared with other forms of energy, hydrogen has more power and is significantly lighter. Lithium batteries The weight is about 50 times that of diesel fuel. This makes it very difficult to travel far (or fast) in a battery-operated boat.  

"Calculated in pounds, hydrogen has almost three times the energy of diesel fuel, and it is more efficient in the use of fuel cells than diesel in internal combustion engines.  

"In short, hydrogen can be compressed into a smaller space and is much lighter than its battery or diesel equivalent. Therefore, with the same space occupied by the battery pack or diesel tank, you can get more Of hydrogen and travel longer distances.

"It is also modular and expandable. There are many fuel cells to generate energy. If one battery goes offline, it can be easily replaced while the other batteries continue to work. It will not cause the need to replace the entire engine. It is simpler, all It consists of components and systems that have been used before and have been proven in the transportation department."

Wille points out that passenger ships are the "ideal starting point" for the maritime industry to adopt zero-emission technologies. "Short routes, consistent schedules, and relatively low energy requirements make ferries an ideal choice," he said. "[Sea Change] provides a unique quiet passenger experience without diesel engine noise or smoke.

"This is a beautifully constructed passenger ferry with a modern appearance. It is the first ferry of its kind in the world that uses hydrogen fuel cell technology. It is equipped with reusable bottling stations, top seats, bicycle racks and state-of-the-art driving. Chamber, the hydrogen fuel cell propulsion system really stands out. In fact, this system is modular and expandable, which is really exciting."

But Wille believes that Sea Change and its pioneering zero-emission power system are just the tip of the iceberg. "This ship is the first step to decarbonize the maritime industry. This technology will have a global impact. This is not just about ferries. This is about a viable future for the maritime industry. This is not only about the potential of cargo ships, but also about improving Recognition of public transportation, daily commuting and the ultimate passenger experience. This technology will directly affect future passenger ferries and water taxis by providing a quieter and sustainable way of commuting, as well as how you commute to work in the future."

The project has received municipal support, including a $3 million grant from the California Air Resources Board (CARB), which is managed by the Bay Area Air Quality Management District (BAAQMD), and the grant comes from the California Climate Investment Corporation, which is A California statewide plan that trades billions of dollars to reduce greenhouse gas emissions, strengthen the economy, and improve public health and the environment—especially in disadvantaged communities. In addition, the project also received the first loan guarantee under the BAAQMD Climate Technology Financing Program, which aims to reduce greenhouse gas emissions by accelerating emerging climate technologies. The Climate Technology Finance team, in cooperation with the California Infrastructure Economic Development Bank and the Northern California Financial Development Corporation (NorCal FDC), led a technical qualification and greenhouse gas analysis, and believed that SWITCH was eligible for loan guarantees. This loan guarantee supports SWITCH and KeyBank in obtaining a construction and term loan of USD 5 million, which enables SWITCH to complete the project.

SSG Michael H. Ollis-The first person in a new class of iconic figures in New York City. The newest ship commissioned by the iconic Staten Island Ferry from the New York City Department of Transportation (NYCDOT) has a lot to praise. The state-of-the-art 320-foot, 4,500-passenger SSG Michael H. Ollis was put into use in October and adopted the classic design features of the highly recognizable Staten Island ferry fleet, but it has been fully updated to improve comfort and safety Sex and efficiency.

Named in honor of the Chief of Staff of the US Army. Michael H. Ollis, a native of Staten Island, was killed in 2013 in Afghanistan to protect his compatriots from suicide bombings. This new ship is the three Ollis designed by Elliott Bay Design Group (EBDG) and built by Eastern The first Staten Island Ferry shipbuilding group in the class ferry series. "The Staten Island Ferry is a globally recognized iconic transport vessel. To commemorate [the new ferry class] one of our late heroes, it makes it even more special," Joey Diceny, President of Eastern Shipbuilding Group Said (Joey D'Isernia).

According to Eastern Airlines, the new ferry is larger and reflects modern technology, making it safer to operate in extreme weather conditions. They are equipped with new customer service facilities, such as more comfortable seats and telephone charging sockets, as well as an oval upper promenade that serves as an outdoor walkway for riders for the first time.

John Waterhouse, EBDG's chief concept engineer, stated that a key priority when designing the Ollis class is to ensure that the new ferry is seamlessly connected to the existing terminal to ensure that the service maintains a "fast schedule." In addition, the design of the new ferry takes into account many "resilient features" because after 9/11 and Superstorm Sandy, these ships will be used to help evacuate New York City if necessary. According to Waterhouse, part of this flexibility is the Voith Schneider propulsion device, which allows “the ship has a lot of maneuverability and control when entering a place that may not be a normal dock.” The new ship is also set up. There are side doors so that they can load passengers on the side instead of just passing through the end of the ferry.

Each ferry is equipped with four ABS electric diesel (EMD) L12ME23B with 750 rpm EPA Tier 4 marine propulsion engines, two of which are an ABS Reintjes DUP 3000 P combined gear and an ABS 36 RV6 ECS/285-2 Voith Schneider A ship powered by a propeller. The power generation is provided by three ABS, EPA Tier 3 marine continuous working diesel generator sets. Caterpillar C18 drives a three-phase generator with 480 V, 60 Hz, rated power of 425 kW, power of 0.8 PF, and speed of 1,800 rpm.

Susquehanna-the newest and most outstanding pilot boat. The proven successful formula of Gladding-Hearn Shipbuilding from Duclos Corporation makes the Chesapeake class one of the most popular pilot boats in the United States.

Since the launch of the series at the Somerset Shipyard in Massachusetts in 2002, more than 20 ships have been delivered to 12 pilot associations across the United States, including the Susquehanna recently handed over to the Maryland Pilot Association. In fact, Susquehanna was the fourth Chesapeake launch delivered to Maryland pilots, and they were one of the first adopters of the design when it was delivered to Patapsco in 2002. By the way, the first ship is still in service and operating well.

Peter Duclos, Gladding-Hearn President and Director of Business Development, said that Susquehanna is the newest and greatest of the proven real Chespeake class, and has been evolving due to a large number of small incremental adjustments and changes over the years. "The Chespeake course is up-to-date and effective today because we have been doing better. Many things are similar, but different from the situation in 2002," Duclus explained. "The result of all these changes is that this ship is faster, but consumes less fuel, and is heavier, more comfortable, and more capable."

Using a deep V hull designed by Ray Hunt Design, the new all-aluminum Susquehanna has a total length of 52.6 feet, a beam length of 16.8 feet, and a draft of 4.8 feet. Powered by two Volvo Penta D16, EPA Tier 3 certified diesel engines, each engine can generate 641 Bhp at 1,800 rpm, and the ship's top speed exceeds 26 knots. The engine turns the five-blade Brunton NiBrAl propeller through the ZF500-1-A gearbox. The Humphree interceptor trim control system with automatic trim optimization function is installed on the beam. The launch is equipped with a 12kW Northern Lights generator set and 100% LED lighting.

The ship’s wheelhouse is equipped with a small suitcase, which is installed on a flat deck in the middle of the ship. The cab is equipped with electrically heated forward-tilting front windows, five NorSap shock-absorbing reclining seats, a luggage rack and console. The front hall includes Porta-Potty, split upholstered benches/bunk beds, tool lockers and safety devices, safety devices, and custom diving suit racks. The interior of the ship is heated and cooled by two 16,000 Btu reverse-cycle HVAC units, and there is also a 2,000-watt 240 VAC heater in the wheelhouse and bow and stern.

Outside the cab are heated side decks and handrails to prevent ice accumulation. The rear ladder leads to the hinged boarding platform on the roof. The control station is located at the beam and there is also a hydraulically driven J-Basket rescue system for pilot rescue operations.

Spindletop-The latest Spindletop, delivered in mid-March by Sabine Pilots, the largest pilot ship in the United States, has a long and deep deep V hull and aquamarine hull, which is absolutely amazing. But perhaps the most striking thing is the size of the boat: 90 feet long and 23 feet wide.

"Spindletop is the largest all-aluminum pilot vessel built in the United States," said Roy J. Breaux, Jr., president of Breaux's Bay Craft, the Loroville shipyard that built this pioneering vessel. "When Sabine Pilots came to Breaux's Bay Craft to build this ship, they demanded luxurious and comfortable interiors, fuel efficiency and stability under severe weather conditions at the bottom of the Gulf of Mexico."

The launch was designed by Breaux's Bay Craft in collaboration with C.FLY Marine Services, a naval construction company in Madisonville, Los Angeles. “The overall size of this ship makes the pilot more comfortable. Hy Back NorSap can accommodate 14 pilots, a navigator and captain, provides reclining seats and four sleepers, and is equipped with a fully equipped kitchen,” Breaux said. The ship is equipped with a three-ton water-cooled air-conditioning system for the driver’s cab, and another two-ton water-cooled air-conditioning system for the lower accommodation, which includes two double double cabins, a bench seating area and a full shower room. head.

“The ship’s speed, fuel efficiency and stability also make it unique,” ​​Breaux said, noting that Spindletop is the first four-screw jet propulsion pilot ship built in the United States. “It is powered by four Scania DI16-82M engines (800 Horsepower, 2,100 rpm) to provide power, dual Disc MGX 5146 gears, Centek water lift muffler and four-wheel Hamilton HM461 water jet, Spindletop sails at 27 knots, with a maximum speed of over 30. Its Ecospeed underwater hull coating provides improvements The fluid dynamics characteristics help to improve performance and save fuel.

Breaux's Bay Craft has been building pilot boats since the early 1970s, but Spindletop is only its second boat with a new generation of deep V bottom. Breaux stated that Spindletop's performance has exceeded 38,500 nautical miles (as of October 20). "This ship has been in service under severe weather conditions, including 8 to 10 feet of sea surface, and has exceeded and exceeded all expectations," Breaux said

Captain Kenneth Leslee Hurd, Sabine’s captain, said: “We went to Breaux to buy a custom-made pilot boat that can maximize the safety and comfort of our 17-mile voyage in the Gulf of Mexico. I am very satisfied with our choice. ."pilot. "Spindletop is equipped with four Hamilton jets, equipped with 4,800 horsepower Scania engines, Humpree proactive driving trim tab, and Breaux's new hull design. She uses the choppers that we run easily every day and last for 3 to 4 feet. Cut. Another important feature of Hamilton is their new AVX (boat mouse) system, which allows operators to easily maneuver the boat in restricted areas."

Hurd said that when designing new launches, operator visibility during pilot transfers was a major priority, adding that Spindletop's heated sintered glass windows allow operators to have 360-degree unobstructed traffic at all times.

For pilot transfer operations, Spindletop has port and starboard boarding platforms on the bow and wheelhouse. The combination of the DB 510 D bumper and aircraft tires surround the perimeter of the ship. For rescue assistance, SeaLift has a customized rescue platform located on a cross beam with a 24V hydraulic device and a cross beam cantilever with a 120V electric winch.

Hurd expects that Sabine Pilots' fifth Breaux-built pilot ship Spindletop will safely disembark and transport the pilots to the ship in many years to come.

Delivered in June, the new 90-ton bollard pull Rachael Allen is the fourth in a series of ASD-90 Z-driven tractors manufactured by Nichols Brothers Boat Builders in Freeland, Washington. It is equipped with the SM300 autonomous by Sea Machines Robotics. -Command and control system. The system's functions include transportation autonomy and remote access to the tugboat's on-board machinery, which allows personnel to manage and support operations anywhere on board or on shore. Navigation obstacle detection and avoidance functions are also standard.

Using remote command and control capabilities, Foss will use its existing fleet monitoring center personnel to monitor the tug’s systems and operating domains through streaming video and sensor data. According to Foss and Sea Machines, the system enables an additional set of eyes and hands to access ship command and control, allowing Foss and Rachael Allen crews to maximize production time, safety and crew welfare

"Although we have not developed a fully autonomous tugboat, the [Sea Machines system] allows our crew to use autonomous functions to make their work safer. Our seafarers are the key to our success, and we believe that Sea Machines products will help them carry out their daily routines. Operations," said Will Roberts, President of Foss Maritime.

Rachael Allen has been delivered with SM300 and fully integrated supporting hardware, but the features of the technology will be activated in phases over the course of six to nine months to ensure full visibility and acceptance by all operational stakeholders. "We are committed to integrating autonomous control... continue to work with our partners in Sea Machines, the U.S. Coast Guard and ABS," Roberts said. "As a safety enhancement measure incorporating new technology, we are testing a tool to support our crew. This tool comes from a system that processes digital information to enhance navigation safety. We feel that the system is a tool for our seafarers to serve customers. Excited. We will work closely with regulators and third-party auditors to thoroughly review the system as we continue to move towards full use of the SM300 on board."

Michael G. Johnson, Founder and CEO of Sea Machines, said: “Although our space has seen many autonomous tugboat prototypes supported by government innovation in Europe, Japan and Singapore, it is worth noting that Foss is launching the first commercial Funding projects in American waters.

"Our technology has been used on merchant ships around the world for nearly three years, and has been supported by thousands of hours of testing and verification. This is another real case of how Sea Machines autonomy is reshaping the way crew members work on the water. "

Sea Machines noted that the Rachael Allen project marks the first time that it has installed an autonomous system on a vessel with more than 5,000 horsepower. Designed by Jensen Maritime Consultants, this 100-foot x 40-foot towing tug will be able to escort the largest tankers and container ships calling at the US West Coast ports it will serve. The ship is equipped with two MTU series 16v4000M65L EPA Tier 4 main engines, which can generate 6,866 horsepower, and are connected to Kongsberg US255 azimuth thrusters.

The MTU Selective Catalytic Reduction (SCR) system optimizes the engine and improves the efficiency. Compared with the previous MTU engine in this power range, the fuel consumption at full power is reduced by 8%, and the fuel consumption is reduced by 14 in a wider operating range. -twenty two%. The design of MTU engine and SCR pays great attention to standard functions such as noise reduction, flexible installation, turbocharger intake silencer and SCR insulation and noise reduction, all of which are combined, without any traditional exhaust silencer. Produce noise levels throughout the ship. MTU engines are also equipped with MTU Go, which is an MTU digital monitoring system and service that allows continuous monitoring of the engine, including all engine parameters and alarms, and trend analysis and broadcast of engine alarms through the MTU Go application.

Rachael Allen is equipped with Mackay Marine Electronics. The towing equipment includes a Markey DEPGF-52R winch with a 750-foot 10-inch synthetic rope at the bow and a Markey DEPC-32 stern winch with a 250-foot 6.5-inch circumference rope rigor. The tug meets the US Coast Guard "M" sub-chapter regulatory standards, and has ABS load line certification and UWILD symbols.
